We still can limit what or how we share and using technologies. For example, I use my cellphone for just texting and using some apps through F-Droid like maps, browsers, etc but never use my phone for banking, logging into online shopping or any other accounts.
I have faraday bags that I can put my phone in if I’m going to places where I don’t want to be tracked like how some retail stores would use customers’ cellphones for locating, pinging, and triangulating. Even people with cellphones just happened to be in the area but not inside shopping at places like malls, they’re still being tracked. I never give away my cellphone numbers to any stores asking for it and I always use cash. As for cameras, if most people start using reflectacles glasses then it may hurt facial recognition industries.
Big tech companies do not listen to customers’ privacy concerns nor respect their boundaries, it’s like they’re being passive aggressive. When someone brings up “nothing to hide”, it reminds me of a senior guy in high school trying to put his hand between legs of a 7th grader girl but she pushed his hand away. Its her rights to tell him no, don’t you agree? Maybe because she thinks he’s creepy (he looks like Gary Ridgeway), too old, or maybe she already has a boyfriend. Doesn’t matter whatever her reasons were, everybody still need to respect others’ boundaries regardless but instead he went across and told her “Oh what matter? Does your cunt stinks?” Same bullshit passive aggressive approach with “nothing to hide?”
The way this world is turning toward to, it better not to have any children being introduced to the population. Would you want to have children on an island that’s full of predators? Same thing. Not just big techs that are predators, other greedy corporations that depend on big tech are too.
